Nowadays hair loss is affecting more and more men and women.
The reasons aren’t just genetic as a time, but now is also affected by the stress of a fast life and by hormones, which are found in meat.
The miniaturization of the bulb takes place due to the transformation of testosterone in its most active metabolite, dihydrotestosterone (DHT). The miniaturization leads to the definitive death of the bulb and to permanent loss of hair. There is still no absolute certainty about the genes causing androgenetic alopecia, but the studies are getting closer to a resolution of the case.
It has been shown that most of the genes involved reside on the X chromosome, that is what the mother conveys to son, or what mother and father convey to daughter. Heredity to a son is greater
about the second X chromosome that the mother has inherited from his father, so the greater transmission takes place by his maternal grandfather to his grandson, rather than from father to son.
